Item Tags

Use the itag:[items tag] parameter to more efficiently search for materials included in the tag.

Tags are a Minecraft concept for organizing blocks, items, and entities into groups. There are quite a lot already defined in Minecraft but you can also create your own via datapacks.

For example, itag:minecraft:pickaxes would search for any pickaxes. See the full list .

You can even supply multiple tags, like itag:minecraft:planks,minecraft:logs.

Defining your own tags would be an extremely powerful way to group materials.

Negation

As of Prism 4.4, this parameter allows negation. Negating an action will exclude results. It is important to note that unlike Prism 3, the syntax has the exclamation point before the colon. You cannot use a negated parameter with its normal equivalent.

Example: /pr l itag!:minecraft:pickaxes (Queries all items except those in the "minecraft:pickaxes" tag)
